Rheological studies of the MA14 alloy

Abstract

The developing direction of the use of magnesium and alloys based on it is their use in medicine. Thisapplication is due to their good biocompatibility with living tissues and physiological environments,as well as the ability to gradually degrade during the operation of the product with the releaseof non-toxic corrosion products. In this work, rheological studies of magnesium alloy MA-14of the Mg-Zn-Zr system were carried out to identify the dependence of temperature-speed processingconditions on structural changes in the alloy. The experiments were carried out at temperatures of 200,300, 400 °C and deformation rates of 1, 60, 600 mm/min by hot precipitation between flat strikersusing an electromechanical measuring system for testing Instron 5982. It was found that deformationat low speeds and a temperature of 200 °C gives a greater effect of hardening of the material and sucha deformation mode should be considered as a basis for subsequent experimental studies.
